.To all whom t may concern; Fig. 5 is aviewin section illustrating a slight Beit known that I, FREEBORN F. RAYMOND, modification of the invention. A 2d, a citizen of theUnited States, residing at l have shown in the drawings only so much Newton, in the county of Middlesexand State of the National machine as is necessary to 5 of Massachusetts, have invented a new and enable the invention to be properly described 5 5 useful Improvement in Heel-Nailing Maand understood. chines, of which the following is a full, clear, A is the frame of the machine. and exact description, reference being had to B is the reciprocating cross-head. b is the the accompanying drawings, forming a part rotary head carried thereby. 1o of this specification, in explaining its nature. b is the bed of the machine upon which the 6o The invention is an improvement upon the jack h2 is mounted to slide, and upon which National heeling-machine, so called; and the post O, on which the carriage C is vertiit relates especially to means for automatcally movable, is supported. The carriage C ically moving the templet-plate and nail-caris vertically movable, as described in Patent I 5 rier plate of said machine, which means are No. 316,894 to Henderson. The carriage has 65 carried by the vertically-movable table or carin its upper part a guideway c for the tem pletriage carrying said templet-plate and nailplate c', and the te1nplet-plate c is held in the carrier plate, and which may be automatically guideway by cap-plates c2, which also furnish operated by connection with one of the shafts the guideway c3 for the nail-carrier plate c4.

This cam has a suitable ing two cam-tracks and a long hub, a supbearing in a bracket d, attached to or made port or bracket for said cam attached to or integral with the table. It also has the long integral with the vertically-movable table, hub d', which receives the upper end of the 2 5 cam-pins connecting the templet-plate and operating-shaft d2, the shaft having a fast 75 the nail-carrier plate with the camgrooves of feather d3, which enters a recess or groove d`L the cam, and when the movement of the cam in the hole of the hub. This permits of the is automatic, as it generally will be, a shaft vertical movement of the cam in relation to connected by bevel-gear with one of the roits operating-shaft.

This employment of a cam in this or the cam may be connected by means of connection does away with the necessity of a vertical shaft extending upward, and upon 85 the hand movement of the plates by the boy which it is vertically movable, or which is veror attendant and with the latches which are tically movable in relation to its operatingnow used for locking both plates in and out gear with the rotary head. This connection of operative position, and does away with the is represented in Fig. 5, where the shaft (l2 40 liability of the breaking of the plates from has at its upper end a bevel-gear (Z8, carried 9o carelessness on thepart of theboyor operator. by a bracket attached to the reciprocating Referring to the drawings, Figure 1 is a cross-head and arranged to slide upon thc view in vertical section taken from the front shaft by means of a fast feather or spline, and to back of the central portion of a National `meshes with a bevel-gear dg, carried on the machine having the features of my invention. end of the rotary head shaft. Vhen this con- 95 Fig. 2 is a view in plan of parts to which the struction is employed, the movement or rotainvention appertains below the dotted line @om tion of the rotary head also causes the rota of Fig. l. Fig. 3 is a plan view of the temtion of the plate-operating cam, whereby the plet-plate and its cam-pin. Fig. 4. is a plan templet-plate and the nail-carrier plate are view of the nail-carrier plate and its cam-pin. automatically moved into and out of opera- Ioo tive position. The operative cam d has two cam-grooves, the cam-groove d10 and the camgroove du. The cam-groove d10 preferably is made narrower and deeper than the camgroove cllland receives a cam-pin d1?, attached to an arm of the templet-plate, (sce Fig. 1,) the cam-pin depending from the arm to enter the groove. This cam-groove is shaped to give the templet-plate the necessary movements-that is, to move it into position after the spanking of the top lift and before the descent of the awls, and to hold it there during the driving of the awls and the driving of the nails, and to withdraw it before the descent of the spanker. The cam-groove du is wider and shallower than the cam-groove d10, and it receives a cam-pin dlg, which depends from an arm (ZM, extending from the nail-carrier plate. This cam-groove is shaped to move the nail-carrierplate into position beneath the drivers after the reeiprocation of the awls, but before the reoiprocation of the drivers, and to then withdraw the nail-carrier plate practically simultaneously with the templet-plate, and to hold it withdrawn until it is necessary to again move it forward.

In Fig. l I have represented the shaft dT as inclined and as connecting the vertical shaft d2 with the crank-shaft e, the crankshaft having the bevel-gear c, which meshes with the bevel-gear e2, upon the lower end of the inclined shaft (Z7. Of course the shaft d2 may have no vertical movement, in which event the cam D is movable upon it, or it may be movable with the cam in the gear which operates it.

When the construction represented in Fig. 5 is employed7 the rotary head b may be turned automatically in any desired way. I prefer, however, to use for this purpose the mechanism represented in Patent No. 317,647 or a modification thereof. Then this organization is employed, it will be seen that the rotary head and the templet and nail-carrier plates are automatically operated in unison.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a heel-attaching machine, the combination of a stationary last or work-support, a table provided with a vertical movement in relation to the last or work-support, a cam mounted upon said table, to be moved vertically with it, and having two cam-grooves, a templet-plate carried by said table, and connected with one of the grooves of the cam by a cam-pin; a nail-carrier also mounted upon said table, to be moved vertically therewith, and connectedwith the second cam-groove of said cam by a cam-pin, the cams being connected to provide the templet and the nailcarrier with the movements speciiied at predetermined times in respect to the height of the table, and means for automatically rotating said cam, as and for the purposes described.

2. In a heel loading or nailing organization, the combination ot' a templet having holes through which nails are adapted to be driven and movable from an operative to an inoperative position; a nail-carrier having holes by which nails are adapted to be fed to the holes of the templet and movable from one position in relation thereto, to another; a single camdisk having two cam-grooves, one of which is connected with the templet and the other with a nail-carrier, whereby upon the rotation of said disk, both the templet and the nail-carrier are adapted to be moved or operated, and whereby they are maintained in their proper relation to each other, as and for the purposes described.

3. In a heel nailing or attaching machine, the combination of a vertically-movable table, a cam mounted upon the table to be vertically movable therewith, and having a camgroove constructed to control the movement of a templet-plate; a templet-plate mounted upon said table,to be vertically movable therewith, and connected by a cam-pin with the groove of the cam, whereby the cam and the plate are movable vertically together with a common supporting-table, as and for the purposes described.

fl. In a heel-nailing machine, the combination of a vertically-movable table, a cam supported thereby, and movable vertically therewith, provided with a cam-groove; a nail carrier mounted upon the vertically-movable table to be vertically movable therewith, and having a cam-pin connected with the camgroove of the cam, whereby the cam and the nail-carrier are movable vertically together, and with their table or support, as and for the purposes described.

5. In a heel-nailing machine, the combination of a vertically-movable table, a cam carried thereby, and having a long hub which extends into a bearing for it, forming a part of the table and movable with it; a slideway across the top of the table over the cam in which a plate is adapted to be horizontally reciprocated, and a shaft for turning said cam partially supported by the table, and having a sliding connection with the cam' or part which actuates it, as and for the purposes described.
